Quizplus · Accepted Answer

Activation of the vestibular system, which is responsible for our sense of balance and spatial orientation, can cause feelings of falling or floating in dreams. This can happen if there is a mismatch between the signals from our visual and proprioceptive systems, which normally work together to provide us with a sense of our body's position in space. In a dream, our brain may simulate a falling sensation by stimulating the vestibular system in this way.
